(1) original Hickock tube tester roll chart. This is for the model 800/800A, but might fit other models such as the 600 or 605. This is from Spring of 1970 (very late revision). In great shape for its age, with no tears or major stains. The paper hasn't even yellowed that much. I recently acquired a garage full (literally) of old audio items, electronics, tubes, and test equipment; please take a (Hickok 800 800A tube tester checker roll chart is the responsibility of Jesse Holland) |
